ADJUSTABLE SCREEN.

SPECIFICATION forming part of Letters Patent No. 549,892, dated November 19, 1895. Application led August 8, 1895. Seriallo. 558,688. (No model.)

To tZZ whom t may concern:

Be it known that I, AGEORGE A. BAUSMAN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Adjustable Screens; and I do hereby declare the following to be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to adjustable screens for windows, dac., and has for its especial object to provide an improved construction for the outside sash whereby the screen may be readily adapted to different sizes of windows and which shall at the same time be fly-tight andbe cheap to make.

To these ends myinvention consists of the novel features hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, therein like letters referring to like parts.

Figure l is a perspective view of my improved screen detached with some parts broken away, the sections of the outside sash being shown as extended sidewise and closed together endwise of the window, or in the vertical direction. Fig. 2 is a horizontal section on the line w of Fig. l. Fig. 3 is a crosssection, looking toward the left, on the line 0c fr of Figs. l and 2. Fig. 4 is a similar view on the line x2 x2 of Figs. l and 2. Fig. 5 is a similar view on the line @asas of Figs. l and 2. Fig. Gis a perspective view edgewise of the sash with some parts broken away and the sash-sections pulled apart. Fig. 7 is an inside end view of the left-hand sash-section shown in Fig. 6.- Fig. 8 is a similar view of the right-hand sash-section shown in Fig. 6. Fig. 9 is a horizontal section on the line :r4 :r4 of Fig. 7, and Fig. l0 is a similar view on the line ai Q05 of Fig. 8.

d a' represent the screen proper, of which parts a is the wire cloth or netting, and a the non-adjustable rigid frame of the screen. The said screen aa is mounted within a suitable seat b of the outside adjustable sash, which is constructed in corner sections, the arms of which unite by telescoping tongue and tongue-seat joints, so arranged as to be iiy-tight at all points of the adjustment. The said cor-ner sections are each composed of spacing-strips c and body-pieces c united by the said spacing-strip c and inside liners c2. The said spacing-strips c form the marginal or outside wall and the body-pieces c' the side walls of the seat b, in which is mounted the rigid frame c' of the screen proper.

For convenience in describing the peculiar tongue and tongue-seat telescoping-joint, by

which the sash-sectionsunite, one of the arms of each section will be called the male arm and be represented by the numeral l, and the other arm of each corner section will be called the female arm and be represented bythe numeral 2, and, of course, it willbe understood that the male arm of any given section co-opcrates with the female arm of the opposite section.

The body-pieces c of each of the arms l and 2 is provided with a pair of tongues c3 c4 and a pair of tongue-seats c5 and c6. On the male arms l the tongues c4 are flush with the inner faces ofthe said body-pieces c', and on the female arms 2 the tongues c4 are flush with the outside surfaces of the body-pieces c. The tongue-seats c5 are on both the male and female arms between the pairs of tongues c3 and c4; but the seat .cG in the case of the male arm l is formed by rabbeting the outer surface of the body-piece, and in case of the female arm the corresponding seat c6 is formed by rabbeting the inside surface ofthe bodypiece. The spacing-strips c on the male arms are of greater length than on the female arm; or otherwise stated the spacing-strip c on the male arm extends to the ends of the tongue c4, while on the female arm the said spacingstrip stops at the outer end of the recess formed by the rabbeted seats c6. This arrangement,of course,provides a seat or groove c7 at the top of the female arm in which the strip c of the male arm may telescope. The inside liners c2 extend to the outer ends of the rabbeted seats c6 on the male arms, and to the inner ends of the tongues c4 on the female arms.

Y The body-pieces c are of the requisite width relative to the spacing-strips c to afford the seat b of the desired width for the desired range of adjustment of the sash in respect to the screen proper.

IOO

From the foregoing description of the parts ot the telcscoping-joints it must be obvious that the male and female arms of the corner sections will unite, as shown best in Figs. l. and 2 of the drawings, with the tongues cij engaging and telescoping in the mortisc-likc seats c5, the tongues el engaging and lapping the tongues c3 in the rabbeted seats c, and the spacing-strip c on the male arm telescoping in the seat c7 of the iemale arm. lVith this peculiar form of tongue and ton guc-seat telescopingjoint, uniting the male and female arms ot the opposite corner sections, it is obvious that the outside sash is adjustable in either or both directions at will, and that in all the adjustments no transverse or other open passage will bc afforded whereby a fly or other insect could enter through the joint into the interior of the building.

The tongues c3, engaging the mortise-likc seats ci', binds the arms together against any tilting action cdgewise of the sash7 and the tongues c4, lapping the tongues e on the rabbeted seats e, serve to lap the joint at both its outside and inside faces up to the top margin of the sash, or, in other words, to a point ilush with thc spacing-strip C. The inside liners c`2 serve as stops to limit the outward movement of the sash-section by the engagement which would occur between the said liners c2 and the inside margins of the screenframe a', and on the female arms the said liners c2 also serve to close the openii1gs,which would otherwise occur at the netting-edges of the rabbeted seats c6 on the female arms when the sections are pulled apart, and thereby close the passage, which might otherwise occur through the said rabbeted seat c and the groove or seat c7 for the spacing-strip. ll'enee, when the screen-sash is in position under the window-sz sh, as all the top openings will be closed by the sash of the window, and all the other outside openings will be closed by the window-casing, it follows that the telescoping joints between the arms of the opposite sections will be ily or insect tight.

Inasmuch as the tongues and tongue-seats necessary for the telesooping joints herein described may be readily formed by the or dinary wood-workin machinery on thc bodypieccs c ot the frame-section, it follows that in virtue of this invention a two-way adjustable sash can bc readily made at small cost.

lVhat I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. The combination with a screen, of an adjustable sash for the same, colnposed ot Corner sections, cach arm ot which is made up of spacing strips c and body pieces c having the tongues ei and tongue seats e c, cooperating to unite opposite sections with telcseop ing ily-tight joints, substantially as described.

2. The combination with the screen c a', of the adjustable sash for the same, comprising corner sections, each composed of the spacing' strip c, the body pieces c having the tongues c3 c4 and the tongue-seats ci c, arranged as dcscribed, and the inside liners c2, all cooperatin g substantially as and for the purposes set forth.

In testimony whereof l affix my signature in presence of two witnesses.
